Subject: [PATCH] dtoverlays: waveshare-panel: Disable new touch controller by
|
|
default
|
|
|
|
Commit e442e5c1ab6b ("arch:arm:boot:dts:overlays: Added waveshare 13.3inch
|
|
panel support") added an extra touch controller for the new panels.
|
|
On systems with old panels, it ends up spamming the kernel log as that
|
|
touch controller isn't there to respond.
